Toallzohom itmay concern:

Be it known that I, ALBERT H. HEAD, a citizen of the United States,residing at Hood River, in the county of Hood River and State of Oregon,have invented certain new and useful Improvements in Sizing-Machines, ofwhich the following is a specification.

This invention relates to sizing machines,

-being adapted particularly to be used in sizing or grading fruits andvegetables.

The primary object of this invention is to provide a sizing apparatuswhich shall be of extremely simple and inexpensive con struction, whichis capable of being operated with a relatively small amount of power,and which will distribute vegetables or fruits of various sizes to theirproper places upon the grading table.

A still further object of the invention is to provide a device of thecharacter mentioned which is of inexpensive construction, and yet whichperforms its functions perfectly and without likelihood of bruising orcrushing the articles graded.

lVith these objects in view, together with others which will appear asthe description proceeds the invention resides in the novel formation,combination, and arrangement of parts, all as will be described morefully hereinafter, illustrated in the drawings, and

pointed out in the claim.

In the drawings 2* Figure 1 is a top plan view of a sizing apparatusconstructed in accordance with the invention,

Fig. 2 is a side view of the improved apparatus, and

Fig. 3 is a sectional view taken upon line 3-3 of Fig. 1.

Referring now particularly to the drawings, 5 indicates a framework ofany suitable size and construction, and which is adapted to inclose andsupport the two sizing rolls. The ends 6 of the frame have suitableopenings arranged in spaced parallel relation, and within which thejournals 7 of sorting or sizing rolls 8 engage. These sizing rolls arearranged in spaced parallel relation, and rotate in the same horizontalplane. I

The rolls 8 in the present instance are of worm or spiral formation, andthe grooves in the said roll increase in depth from one end to the otherthereof. It will be ob- WHIEE:

served that :the rolls are so arranged .within the supporting frame thatthe ridge portions of the spirals will correspond with each other, sothat the grooved portions of the said rolls will form openings betweenthem. By having the grooved portions of the spirals increasing in depthfrom one to the other end of the cylinder or spiral it is obvious thatthe openings will correspondingly increase in size.

Each of the spiral members is provided at one end with a gear 9 in meshwith the gear of the opposite roll, and it is obvious therefore thatrotation of one of the rolls will be transmitted to the other roll. Anypreferred means may be-employed for imparting the necessary movement tothe rolls, one of the journals of one of the rolls being extended andprovided with a belt pulley 10, over which a belt 11 is trained.

In operation, the frame and the grading spirals or rolls are arrangedabove the grading table, and the said rolls are set in motion throughthe belt 11. The articles to be graded or sized are delivered to therolls at the end where the grooves therein are shallowest. The rotarymovement of the rolls causes the articles to be carried toward theopposite end thereof, and as the articles progress, they will dropthrough the openings corresponding to their sizes. The articles thusdeposited upon the grading table will be properly separated and may beremoved to suitable boxes when desired.

From the foregoing it is obvious that I have provided a sizing apparatuswhich is of extremely simple construction and which will efiicientlyperform its functions. It is preferred that the rolls be so constructedas not to present any sharp edges, so that danger of bruising orotherwise injuring the fruit will be obviated.

While the present is a disclosure of the preferred embodiment of theinvention, it is to be understood that the invention is not limitedthereto, as various changes in the minor details of construction,proportion, and arrangement of parts may be resorted to if spirit of theinvention as defined by the appended claim.

I claim V In a device of the class described, a pair of spirals arrangedin spaced parallel relation with their outer peripheries close todesiredwithout departing from the gether and spaced apart an equal distance ofthe spirals, and means for rotating said 10 throughout the length of thesaid spirals, spirals.
